> Fix the overflow problem of Long type in SetSparkReducerParallelism
> -------------------------------------------------------------------
>
> Key: HIVE-17010
> URL: https://issues.apache.org/jira/browse/HIVE-17010
> Project: Hive
> Issue Type: Bug
> Reporter: liyunzhang_intel
> Assignee: liyunzhang_intel
> Attachments: HIVE-17010.1.patch, HIVE-17010.2.patch
>
>
> We use
> [numberOfByteshttps://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/spark/SetSparkReducerParallelism.java#L129]
> to collect the numberOfBytes of sibling of specified RS. We use Long type
> and it happens overflow when the data is too big. After happening this
> situation, the parallelism is decided by
> [sparkMemoryAndCores.getSecond()|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/spark/SetSparkReducerParallelism.java#L184]
> if spark.dynamic.allocation.enabled is true, sparkMemoryAndCores.getSecond
> is a dymamic value which is decided by spark runtime. For example, the value
> of sparkMemoryAndCores.getSecond is 5 or 15 randomly. There is possibility
> that the value may be 1. The may problem here is the overflow of addition of
> Long type. You can reproduce the overflow problem by following code
> {code}
> public static void main(String[] args) {
> long a1= 9223372036854775807L;
> long a2=1022672;
> long res = a1+a2;
> System.out.println(res); //-9223372036853753137
> BigInteger b1= BigInteger.valueOf(a1);
> BigInteger b2 = BigInteger.valueOf(a2);
> BigInteger bigRes = b1.add(b2);
> System.out.println(bigRes); //9223372036855798479
> }
> {code}
